The goal of this study was to determine the effects of soil phosphorus (P) status on litter decomposition rates using two factors: soil texture (with associated differences in soil P pools) and fertilization, ...

The calibration of a model of flow, temperature, and water quality in the
Tualatin River, Oregon, originally calibrated for the summers of 1991 through
1993, was extended to the summers of 1991 through ...

To determine whether there are differences in the relative capacity of
communities to accumulate nutrients N and P standing crops were
measured following fertilization in two alpine tundra communities. ...

The Chesapeake Bay Program Nutrient Point Source Database contains data from

Ridge Saddle, in the City of Boulder Watershed. ...

The effects of nitrogen, phosphorus, and nitrogen+phosphorus
fertilization on phenology of alpine plants was examined. This was a
preliminary study to determine if the phenologies of dry meadow plants ...

We studied drought effects on ecosystem functioning in a semiarid
grass-shrub steppe South of Argentina. We designed a 2-year rainfall
manipulation experiment where we decreased water input with rainout ...

all trees left on site. During ...

In September 1996, a water-quality study was done by the U.S. Geological
Survey, in coordination with the U.S. Forest Service, in headwater streams of
Steamboat Creek, a tributary to the North Umpqua ...

This experiment began in 1966 on a site that was originally
forested. Later, the crops grown on the site were pea and wheat.
The treatments and rotations in the experiment are: Rotation 1 -
